I have hashmap method that read .txt file and count "Ship","TaxPay","credit" words how many times they appeared. the problem is the count number is incorrect.

This is the pay.txt file

Ship TaxPay Ship TaxPay Ship TaxPay Ship TaxPay credit Ship credit Ship credit Ship Ship

This is my code:

public class calculatecount {

public static void main(String[] args) throws IOException {

for(String i: readFile().keySet()) {

System.out.println("Key: "+i+" Value: "+readFile().get(i));

}

}

public static HashMap readFile() throws IOException{

int count=0;

File file=new File("/Users/Desktop/pay.txt");

BufferedReader br = new BufferedReader(new FileReader(file));

HashMap ct=new HashMap ();

String st;

String []myList= {"Ship","TaxPay","credit"};

while((st=br.readLine())!=null) {

for(int i=0;i

Pattern pre=Pattern.compile(myList[i]);

Matcher prec=pre.matcher(st);

if(prec.find()) {

ct.put(myList[i], count++);

}

}

}

return ct;

}

}

The out put is:

Key: TaxPay Value: 7

Key: Ship Value: 14

Key: credit Value: 12

But it should be:

Key: TaxPay Value: 4

Key: Ship Value: 8

Key: credit Value: 3
